> How long does it usually take to get consumer products of new PCIe specs?
Personally I'm expecting this spec to drive pcie 5.0 adoption into consumer space.
Tbh consumers dont need this througjput. But given that consumer space has remained stuck around 20x lanes off the cpu (plus some for the chipset), the 5.0 and 6.0 specs will be great for those wanting to build systems with more peripherals. A 1x 16GBps link is useful for a lot.
I'd be leery of dismissing the potential consumer demand. That much throughput could be put to good use for a myriad of personal and business functions, and software trends to filing whatever hardware can provide. It's like every prediction about users not needing X amount of ram or cpu or dpi or network or storage space.
Having that much throughput suggests paging and caching across multiple disks, or using giant models (ml or others) with precomputed lookups in lieu of real-time generation. At any rate, all it takes is a minor inconvenience to overcome and the niche will be exploited to capacity.

Those sound to me like situations where latency will be the bottleneck, even on something like PCIe 3.0 x4.
I can currently only name one consumer use for these super high speed data transfers, and that's loading 3d assets and textures from SSD to GPU in real time based on where you're looking.
Signal integrity is becoming a serious issue for these higher speed links. So it's a compromise between how many traces you need vs. the signal speed.
For the server market, GPU's and other accelerators, high speed NIC's and SSD's have an unending appetite for bandwidth, so there I expect a lot of interest. But I think we'll see an increasing gap between this and the consumer market, for better or worse.
